Hi all,
after have looked for many topics I have to ask you an help to do a simple 3D in plot in igor...
I have a mztrix 5x5x5 how can I make a 3dimensional plot of them?

Thank you...G.
Hi, thank you for your reply, but please be patient but I am not still able to make my 3D plot...
I attach the image of my table...
is possible to realize a surface plot of this data?
in the figure, Vg is the x axis, c (the last) is the y and all the other are on z....

Thank you very much for your help...G.

Igor is quite hard !
I am not sure to have gizmo installed correctly: if I open "data browser" my Igor shut down....:-)
More I have not the same sub-menu I have seen in the video tutorilas...

How can I make an update or upload the library?

Thank you!!!! G.

It looks like this will take some extra effort as you don't have the required three waves: x,y,z. Instead, you have x, y, and 5 separate z waves.

You need to combine the z waves and modify x and y accordingly so you have three waves where each row represents a xyz point in space. (see attachment)

Next, you can make the triplet wave, and generate the gizmo plot. This makes a scatterplot. To make the 3D plot look better, you will need to append a surface plot. The surfaceplot wave can be generated from your triplet wave using ImageInterploate (the Voronoi method usually works for me). Use the /S flag to specify the resolution of the image generated.

ImageInterpolate/S={0, 0.05, 1, 1e-6, 5e-6, 1} Voronoi Tripletwave

I hope I did not sound impatient -- just tried to point you to some resources that demonstrate how easy it is to create 3D plots.

You need to organize your data in the form of a triplet wave. A triplet wave has 3 columns where each row specifies the XYZ triplet of a single data point. Since you are dealing with a relatively small set of data you can create the necessary wave on the command line (e.g., make/N=(#rows,3) tripletWave ) and then fill the wave using copy and paste using tables.

After you create the triplet wave you should ask yourself if a surface is indeed the appropriate representation for the data or if, for example, a scatter is more suitable. If you still want to display a surface then follow the instructions in the video tutorial. If you want to display a scatter then you can select the icon corresponding to the triplet wave in the Data Browser and choose Gizmo Plot from the contextual menu.

If you have a problem with the Data Browser you need to report it to support@wavemetrics.com. The last crash reported on the Mac was years ago in a version of IP5 and can be solved by a simple update of the XOP. Still I suggest that you contact support and report all the relevant details including the version of IP and the OS that you are running so we can investigate further.
